Summary

Due to the development and easy availability of ultrasonography devices, regional nerve blocks are routinely used by anesthesiologists among multimodal analgesia techniques. Interscalene and supraclavicular nerve blocks are the leading regional anesthesia techniques for shoulder surgeries. However, due to the phrenic nerve involvement and loss of motor function in the upper extremity in these block techniques, new nerve blocks have been developed and used for postoperative analgesia. One of the blocks that has been used increasingly in shoulder region surgeries and does not cause phrenic nerve involvement is the shoulder anterior capsule block (SHAC). The aim of this study is to compare the postoperative analgesic effects of interscalene nerve block and SHAC block in patients undergoing arthroscopic rotator cuff repair surgery.

Conditions

  • Pain Intensity Assessment
  • Interscalene Nerve Block
  • Shoulder Anterior Capsule Block (SHAC Block)
  • Pericapsular Nerve Group Block (PENG)

Interventions

PROCEDURE

Interscalene Nerve Block

After sterile conditions are provided with the patient in the supine position, the brachial plexus will be identified in the supraclavicular fossa above the clavicle with ultrasonography. The transducer will be directed cephalad and 20 cc 0.5% bupivacaine will be applied to the interscalene space with a 50 mm block needle from the point where the C 5-6-7 nerve roots give the impression of a rosary bead between the anterior and medial scalene muscles.

PROCEDURE

Shoulder Anterior Capsule Block

In pericapsular nerve block application, the patient will be placed in a supine position and the arm will be externally rotated and abducted to 45 degrees. After sterile conditions are provided, the humerus head, the tendon of the subscapularis muscle and the deltoid muscle above it will be identified with ultrasonography. 15 cc of 0.5% bupivacaine will be injected into the interfascial space between the deltoid muscle and the subscapularis muscle with a 22gauge 50 mm block needle. Then, the block needle will be directed deep into the subscapularis muscle and another 5 cc of 0.5% bupivacaine will be injected under the subscapularis muscle.
